All I need is the main.cpp file Programming Specifications: Task: Two files have been provided (wordcounter.h and wordcount.cpp). You must open a text file, read in each word until end of file, add each word to the WordCount library and print the report. Your program must request a filename of a text file that contains words to count. You must check to see if it is a valid file and issue an error message if not and request a new file name until a valid one is entered. You must have at least one function that either passes in a parameter and at least one function that returns a value. You can have a single routine that does both. You must declare the class object properly, use AddWord() to add the word to the catalog and use PrintSummary() to produce the output. Design Considerations: The file will contain only words (no punctuation or special characters) less than or equal to 13 letters. There will be no limit to the number of words. You must open the file and read each…
1. Write a program named program61.py This program will have three functions, the main() create() and retrieve(). main() will call: create() and main() then calls retrieve() create() will prompt the user to enter any number of course name | grade values. The course name ,AND calculated class GPA ( not the class grade ) are the written one value per line to a file named grades.txt ( review example of grades.txt below! ). Pressing Enter with no input value on the course name will exit the loop, close the file, print "File was created and closed" and return the bool value True to the main(). See Simple GPA Tip below. retrieve() will open and read grades.txt. The function then will print the course names and Class GPA as shown below. The average of all class GPA values should be calculated and displayed to two decimal places and then return variable used for the GPA average to the main() . See sample run below in which 2 course names were entered, but note that more or fewer…

Answer the given question with a proper explanation and step-by-step solution. 1- Write code that does the following: opens an output file with the filename number_list.txt, uses a loop to write the numbers 1 through 100 to the file, then closes the file.
step 1: Write a python program that will ask the user for their grocery list, one item at a time, and will write it to a file called groceries.txt. The program should create a new file called groceries.txt that will contain all of the user’s groceries when opened. Step 2: Modify the python program that creates a groceries.txt file so that if the user’s favourite fruit is not on the list, the program will append it to the end of groceries.txt file.
1. Create a file that contains 20 integers or download the attached file twenty-integers.txttwenty-integers.txt reads:12 20 13 45 67 90 100 34 56 89 33 44 66 77 88 99 20 69 45 20 Create a program that: 2. Declares a c-style string array that will store a filename. 3. Prompts the user to enter a filename. Store the file name declared in the c-string. 4. Opens the file. Write code to check the file state. If the file fails to open, display a message and exit the program. 5. Declare an array that holds 20 integers. Read the 20 integers from the file into the array. 6. Write a function that accepts the filled array as a parameter and determines the MAXIMUM value in the array. Return the maximum value from the function (the function will be of type int). 7. Print ALL the array values AND print the maximum value in the array using a range-based for loop. Use informational messages. Ensure the output is readable.

Milestone #1 - Ask Quiz Type In a file called main.py, implement a program that asks the user for a quiz type and prints the file name for that quiz type. The program should have one input prompt: the integer value of the personality quiz number. Your program should print the welcome message and the list of the personality quizzes, ask for the test number, and then print the file name. You are required to use the provided dictionary with the personality quizzes names. The list of the personality quizzes should be printed in alphabetical order. See example below. Welcome to the Personality Quiz! What type of Personality Quiz do you want to run? 1 BabyAnimals 2 Brooklyn99 3 Disney 4 Hogwarts 5 MyersBriggs 6 Sesame Street 7 - StarWars 8 - Vegetables
In Python Write a program that consists of (at least) two function: A function that creates and saves data in a file. The saved data represents exam grades. In the function, you will create n random numbers in the range [0,100], where n is the number of students. The function can be called as follows: createFile(filename, n) Main function, in which the user inputs the file name and the number of students, then the main calls function createFile. The main should perform validation for n (should be > 0), and the filename (should end with .txt). I will explain how to validate strings in the coming lecture. Hint: a good developer will write four functions to solve the problem.
